Research points to obesity as a potential cause of vitamin D deficiency (not the other way round)

Previous research has found a link between lower levels of vitamin D and higher body weight, causing some to speculate that vitamin D deficiency may be a factor in obesity. The problem with this sort of evidence is that while it can show a link between vitamin D deficiency and, say, obesity, we can’t tell […]

Vitamin D appears to have given my mum a whole new lease of life

2 or 3 weeks back, I was having a conversation with my 79-year-old mother regarding her mobility. She is, ordinarily, a bit of a force of nature, with abundant energy and still fending entirely for herself (with the help of my father) in all aspects of her life.

Has scare-mongering around skin cancer contributed to the resurgence in rickets?

I spotted this article earlier this week in the UK national newspaper The Telegraph. It concerns warnings about vitamin D deficiency, and particularly how the less-than-brilliant summer we had in the UK can only add to our woes in this respect. The end result may well be an upsurge in the rates of rickets (poorly […]

Higher levels of vitamin D are associated with a reduced risk of a variety of health issues including heart disease, type 2 diabetes and several forms of cancer.

It’s early October, and here in the UK there’s a distinct sense that the days are becoming ever-shorter and the nights are drawing in.

The dark side of sunscreens

Here in London, UK, the weather today has been quite summery. And it’s this time of year where we generally begin to see a rash of articles in the press warning us about the perils of sunlight and the need to slather on our sunscreen.

Taking vitamin D may assist fat loss and reduce risk of chronic disease

There is a ton of research which links higher levels of vitamin D (and/or increased sun exposure) with reduced risk of a range of conditions including diabetes, multiple sclerosis, several forms of cancer and heart disease. These studies are voluminous, and tend to be quite consistent, but they still can’t tell us for sure that […]

Can shining a light into the ears combat ‘winter blues’?

The shorter days and general lack of sunlight in the winter can leave some of us prone to low mood and lack of vitality or even full-blown depression in the form of ‘seasonal affective disorder’ (SAD). A reasonable and often-effective strategy for overcoming these issues is light therapy, delivered by devices which simulate sunlight. However, […]
